Application filed :October 18, 1921. Serial No. 508,449.

To all whom it; may concern? Be it known that I, SARAH ROBINSON, a'

roughened member adapted tor be readily` removedfrom the frame whenworn, and as readily replaced with a newroughened member, together withsimple, compact and eiiicient means for positively :securing-said memberin Working position inthe frame so that there is no liability of theroughened member being casually displaced incident to the use of thewashboard, and yet when desired or necessary the roughened member may bereadily released for removal and when a new roughened member is placedin the frame the new member may be expeditiously and positively lockedin position.

Manifestly when the roughened member is rendered useless through Wear,the frame is saved and may therefore, be used in succession with anumber of roughened mem'- bers. v

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a front elevation of my novel washboard, with parts in section.

Figure 2 is a cross section ofthe same on. the line 2-2 of Figure 1.

Figure 3 is an enlarged perspective of the locking bar per se.

Figure 4 is an enlarged detail section taken on the line 4-4 of Figure1.

Figure 5 is an enlarged detail Section taken in the same plane as Figure2.

Similar numerals of lreference designate corresponding parts in all ofthe views of the drawings.

The roughened member 'l of my improvement is of plate-like form, and isribbed or otherwiseroughened as indicated by 2. On one o-f its edges theSaid member 1 is provided with a handle 3 to facilitate itsmanipulation, and at 4 it is provided with onehalf of a groove ofdovetail form in cross section, See Figures 2 .and 5. The said grooveportion 4 extends throughout the height of the memberl at a' pointvadjacentL n to the handle-bearing edge of they member as will beunderstood by comparison'of Figures1,2and5.

The said roughened member ly is remov-,` ablyrsheathed in a receptacle5in the frame 6, the said receptacle being open at the front side-'andratone' end and being defined-'by the back wall 7,one side bar Sadtherupper and lowercr'oss bars 9 and 10 ofthe frame.

It will also be-noted that flanges'v 11 are provided on the upper andlowerv cross-bars y9 and 10 so asto prevent the roughened mem` ber 1jfrom casually" moving forwardly from thereceptacle. vFlanges 1P forfthesame purpose are also'provided on' the sidebars of j the frame. ,L Inthe side bar'12'o'ftheframeis provided a groove anda groove portion forcooperation with the groove portion 4 in the roughened member 1 andtheplocking bar 13. From the upper end of the saidside bar 12 to theupper endv of the `receptacle 5 the groove in the side bar 12 is ofcorn`plete dovetail form in cross section as indicated by 14 in Figure 4, andfrom the lower end of the receptacle 5 tothe lower closed end of thegroove, the groove is of complete fdovetail' form in cross Section, thelatter groove portion being designated by 15 in .y Figure 1. From apoint ,opposite the upperv end of the receptacle 5 to a point opposite lened member 1 it is simply necessary ytoV Withdraw the locking bar 13upwardly out of the frame and out of the member 1 when n the said member1 may be withdrawn endwise from the frame. A new roughened member 1 maythen be introduced endwise into the receptacle 5 of the frame 1, andwhen said member lis completely inserted, it is simply necessary toreplace the locking bar 13 in eng-agement with the frame l and'roughened member 1 `when thenew roughened member will be securely lockedin position. v c

lt will be apparent from the foregoing that the frame and the lockingbar of my improvement are adapted to be used in conjunction with aplurality of roughened members l. in successionyso that when arougliened member l is impaired by Wear, the frame yand the locking bar13 are not rendered useless. @n the other hand when a roughened member lis rendered useless through Wear, the said roughened member l alone needbe discarded, which obviously contributes to econon'iy in practice.

lt will also be apparent from the iioregoing that notwithstanding the'Facility with which the locking bar 13 may be introduced and removed,the said bar 13 is highly eilicient in .positively securing theremovable roughened member l in the frame, and is so 'arrangedVrelatively to both frame and reughened member that the Washboard as aWhole is not rendered cumbersome.

l haveentered into a detailed description ot the construction andrelative arrangement of parts embraced in the present and preerredembodiment of my invention in order toimpart a full, clear, and exactunderstanding of said embodiment. l do not desire, however, to beunderstood as coninin myself to the said specific construction anrelative arrangement of parts inasmuch as in the future practice ot theinvention various changes and modifications may be made such as fallWithin the scope of my invention as defined in my appended claim.

Having described my invention, what I claim and desire to secure byLetters Patent, t:-

In a Washboard, the combination With a frame having a receptacle open atone side edge of the iframe and also having a groove extendinglengthwise of the frame adj ac ent to said side edge, a roughened memberre* movable edgeivise from the receptacle of the frame and having alengthwise groove to register and cooperate With that in the frame, anda locking bar arranged length- Wise of the Washboard removably sheathedin the said grooves of the frame and rougl1- Y ened member topositivelyk secure the latter in the receptacle of the former.

ln testimony whereof, I aix my signature.

SARAH RGBNSON.
